Building Regulations Updates
Revised regulations for building came into effect on June 15th, 2022. These regulations incorporated a provision for enhanced insulation in loft conversions. Consequently, in the majority of situations, the thickness of insulation below the rafters has been increased. As a result, the minimum height requirement to the tallest point of the existing roof should be 2.4m.
